Fluorescent lights work just fine on DC voltage, BUT one needs a current limited power source to stabilize the circuit against the negative resistance of the gas discharge. This can be done with either a resistor or an electronic circuit. The resistor solution is too lossy because excess voltage from the dc csupply has to be converted to heat across the resistor. Electronic switching supplies could supply a fluorescent light with a dc voltage and current without the losses. But that's technological overkill and most circuits still supply AC.

How does an led light bulb work?
LED's (Light Emitting Diodes) work on DC current, not AC, so the AC needs to be stepped down to an appropriate voltage via a transformer (probably only a few volts), converted to DC via a rectifier and filter (to smooth out the ripple current). there are a constant driver in side the 120V AC led light bulb , this driver transfer the AC to DC, so the led could work with DC.
Can DC series motor work on ac and DC and why?
A dc series motor can work on dc and ac because dc motors are totally reversible.
Is DC or AC used to light a light bulb in the home?
AC...
Can dc bulbs work on ac?
Yes- ac or dc makes no difference to a regular light bulb. However, it must be the correct voltage. DC bulbs used on a car are 12 volt, and household AC current is 120-240 volts.
Is fluorescent lights fixtures ac or dc?
The basic fluorescent light fixture is AC, although there are fluorescent lights powered by DC.
Can DC bulbs work on AC current?
Yes- ac or dc makes no difference to a regular light bulb. However, it must be the correct voltage. DC bulbs used on a car are 12 volt, and household AC current is 120-240 volts.
How does DC to ac power supply work?
If having DC and AC is required then a PWM pulse width modulator is required to chop the DC to make AC
Are Christmas lights ac or dc current?
Christmas light have always been AC.
What is difference between ac and DC bulb?
we can check the dc with the help of tester give the reasonAnswerThere is no such thing as an 'AC light bulb' and a 'DC light bulb'. A light bulb doesn't care whether it is subjected to AC or to DC.
Do laptop work on ac or DC and how?
A laptop runs on DC. Either from the battery, or the external power supply, which converts AC power to DC.
Can a dc motor work in ac?
No it cant
Is a 360 watt 86 volt halogen light ac or DC?
A halogen bulb works equally well with AC or DC.
